Information about creating and working with lights in the scene.
Start by placing a key light to illuminate the objects, then fill lights to better define the shapes of the objects in the scene. After you place a light in the scene view, you can switch it with a different type of light in the operation controls toolbar, as well as modify the light color. This can also be done on the Light tab in the parameter editor.
Types of lights
The following are brief descriptions of the different buttons on the Lights and Cameras tab. Each light tool puts down the same light node, but with different specifications. However, the Ambient Light puts down an Ambient Light node since its unique from the other five.
Emits light from a point in all directions and is similar to a light bulb.
Radiates a cone shaped beam of light from a point in a certain direction.
Automatically distributes a number of light sources over a specified area. There are five area light shapes to choose from.
Emits parallel rays of light, which are similar to the rays of the sun.
Casts light into the scene as if from a surrounding hemisphere or sphere. The default environment light is a hemisphere; however, you can make it a full sphere by turning on the Use full sphere for environment checkbox on the Area Light Options sub-tab of the Light tab in the parameter editor. You can also change the sampling density in the Area Samples parameter on the Area Light Options sub-tab of the Light tab in the parameter editor.
The position of the light does not matter. You can rotate the light object to orient the light source. With no rotation, hemisphere lights are oriented to cover the region above the XZ plane.
An environment light may use a texture map to provide illumination from an environment map. With no rotation, the environment map is oriented so that the top face aligns with the positive Y axis.
Emits light from all directions to illuminate the scene (source-less light). For specific parameter information, see the Ambient Light node help.
For specific parameter help see the light.
Placing lights in the viewer
|Place lights in a specific location in the scene view|
|Place lights at the origin|
|Place a light by looking through it|
Allows you to control the delta and cone angle.
Allows you to set the near and far clipping planes and the focal length.
Use the view keys to move a light
Lock the light to the view by clicking the Lock camera/light to the view button, which is located on the toolbar on the right side of the view. You can also lock the light to view by by turning on Tie Camera (or Light) to View in the camera menu.
Unlock the light to place it.
